Other Information

**Key Characteristics:** SNRPD3 is a 93-kDa protein encoded by the U6 snRNA gene and is a component of the U6/U5 tri-snRNP complex, which is involved in the second catalytic step of RNA splicing. SNRPD3 shares sequence similarity with other Sm proteins and is characterized by a unique RNA-binding domain. The protein is predominantly expressed in cells of hematopoietic origin, including erythroid progenitor cells, myeloid leukocytes, and medullary thymic epithelial cells. **Pathways and Functions:** SNRPD3 is involved in various cellular processes, including: 1. **RNA Splicing:** SNRPD3 is a key component of the U6/U5 tri-snRNP complex, which is responsible for the second catalytic step of RNA splicing. This process involves the recognition and excision of introns from pre-mRNA, resulting in the generation of mature mRNA molecules. 2. **Immune Response:** SNRPD3 has been implicated in the regulation of immune responses, particularly in the context of viral infections. For example, SNRPD3 has been shown to modulate the host translation machinery in response to SARS-CoV-2 infection. 3. **Cell Differentiation:** SNRPD3 is expressed in cells of hematopoietic origin and is involved in the regulation of cell differentiation, particularly in the context of erythropoiesis. 4. **Disease Pathogenesis:** SNRPD3 has been implicated in the pathogenesis of various diseases, including cancer, where it is often overexpressed and associated with poor prognosis. **Clinical Significance:** SNRPD3 has significant clinical implications, particularly in the context of: 1. **Viral Infections:** SNRPD3 has been implicated in the regulation of immune responses to viral infections, including SARS-CoV-2. Its expression levels may serve as a biomarker for predicting disease severity and outcome. 2. **Cancer:** SNRPD3 overexpression has been observed in various types of cancer, including leukemia and lymphoma. Its role in cancer pathogenesis and prognosis warrants further investigation. 3. **Immune-Mediated Disorders:** SNRPD3 has been implicated in the regulation of immune responses in autoimmune diseases, such as rheumatoid arthritis and lupus. Its expression levels may serve as a biomarker for predicting disease activity and response to therapy. In conclusion, SNRPD3 is a critical component of the spliceosome complex and plays a pivotal role in RNA splicing, immune response, and cell differentiation. Its clinical significance is underscored by its involvement in various diseases, including viral infections, cancer, and immune-mediated disorders. Further research is warranted to fully elucidate the function and clinical significance of SNRPD3.
